This method for signing is constructed using only idealized commitments and multiplication, and can be instantiated under many different assumptions, yielding different time\/bandwidth tradeoffs. Abhi constructs 3 or 2 round signing protocols (with pre-processing) that run in milliseconds, thus eliminating long standing bottlenecks in round complexity for this problem without incurring additional costs elsewhere.\n\nThis is joint work with Jack Doerner, Yash Kondi, Eysa Lee.\n\nAbout the presenter \nAbhi is a professor at Northeastern University and pseudo-engineer at Google whose demeanor has often led students to confuse him with that other famous Indian comedian who is Master of None.\n\nAbout a16z crypto research\na16z crypto research is a multidisciplinary lab that works closely with our portfolio companies and others toward solving the important problems in the space, and toward advancing the science and technology of the next generation of the internet.

We explore the once-impossible innovations people are building now, how they work, and what they make set in motion. Plus, conversations and explainers examining the promise, tradeoffs, and open questions at the forefront of exponential technological change. \n\nExpect to hear from the founders, builders, and researchers remaking established industries and creating entirely new ones. Our interests range from the practical details of building a company to the early contours of a post-AGI world, with room for the odd, audacious, far-fetched, and unclassifiable. \n\n***\nPosts should not be considered investment advice or an advertisement for investment services.
